Distance Separated Simultaneous Sweeping: Efficient 3D Vibroseis Acquisition in Oman

Distance Separated Simultaneous Sweeping (DS3) is one of a number of techniques developed by BP for efficient land seismic operations. DS3 relies on the Vibroseis source separation distance being chosen to allow sufficient travel time such that the first break noise, or reflection signal, will reach the midpoint crossover later than the time of interest for target horizons. The DS3 records are thus uncontaminated by simultaneous source noise for all levels down to, and including, the target horizon. Implemented at field wide scale across Block 61 in Oman, the DS3 technique achieved world record acquisition production rates and produced excellent data quality.
